ARM: 7648/1: pci: Allow passing per-controller private data (352af7d4) · Commits · 戴 / test

In order to allow drivers to specify private data for each controller, this commit adds a private_data field to the struct hw_pci. This field is an array of nr_controllers pointers that will be used to initialize the private_data field of the corresponding controller's pci_sys_data structure. Signed-off-by:
